I have a character in my campaign who is having this exact issue that's discussed here: <a href="https://app.roll20.net/forum/post/6133929/duplicate-character-in-journal" rel="nofollow">https://app.roll20.net/forum/post/6133929/duplicate-character-in-journal</a> I have many APIs being used but it looks like the solution for this previous user was to have the character made unique again in the database on the back end. The character name is Galladia the Unrested in the campaign titled One-Shots.
